Metric Quotes
[T]he degree of confirmation assigned to any given hypothesis is sensitive to properties of the entire belief system ... simplicity, plausibility, and conservatism are properties that theories have in virtue of their relation to the whole structure of scientific beliefs taken collectively. A measure of conservatism or simplicity would be a metric over global properties of belief systems.

Imagine a universe made up not of things in space and in time, but of patterned flows extending throughout its reaches. What flows is a mysterious, nonindividualized something we call energy. It flows along pathways structured by the metric of integral space-time. It flows smoothly, without crinks or wrinkles, over vast stretches of this cosmic matrix, and it becomes contorted in some regions.

Perceptual space is not a special space in addition to physical space, but physical space which we endow with a special subjective metric. ...apart from the definition of congruence in physics and that based on perception, there is no third one derived from pure visualization. Any such third definition is nothing but the definition of physical congruence to which our normative function has adjusted the subjective experience of congruence.
Hans Reichenbach
You only have to wade through a metric measure or two of European prose, culled from its directives, circulars, reports, communiqués or what pass as debates in its 'parliament', and you will quickly understand that Europe is, in truth, synonymous with bureaucracy – to which one might add 'to', 'from' and 'with' bureaucracy if one were so minded.

My dissertation for the Ph. D. degree at the University of Michigan was on applications of vectorial methods to metric geometry (in the sense of the Menger school), especially with a view to the merging of metric geometry in that sense with differential geometry. Professor S B Myers at the University of Michigan sponsored my dissertation, but I was particularly close to R L Wilder there.

A psychological space is established for any set of stimuli by determining metric distances between the stimuli such that the probability that a response learned to any stimulus will generalize to any other is an invariant monotonic function of the distance between them. To a good approximation, this probability of generalization (i) decays exponentially with this distance, and (ii) does so in accordance with one of two metrics, depending on the relation between the dimensions along which the stimuli vary. These empirical regularities are mathematically derivable from universal principles of natural kinds and probabilistic geometry that may, through evolutionary internalization, tend to govern the behaviors of all sentient organisms.

In 1917 Levi-Civita discovered his celebrated parallelism which is an infinitesimal transportation of tangent vectors preserving the scalar product and is the first example of a connection. The salient fact about the Levi-Civita parallelism is the result that it is the parallelism, and not the Riemannian metric, which accounts for most of the properties concerning curvature.

Trending topics helped make Twitter a more relevant metric of what the world was talking about at any given moment. Google has worked for years in the space, most notably with Google Trends and Hot Searches, but Google+ offers the search giant the ability to see what is truly trending in real time.

'Hound Dog' took like twelve minutes. That's not a complicated piece of work. But the rhyme scheme was difficult. Also the metric structure of the music was not easy. 'Kansas City' was maybe eight minutes, if that. Writing the early blues was spontaneous. You can hear the energy in the work.
